Not only does Frank know how to squeeze every last bit of performance out of PostgreSQL and Linux -- he is happy to explain his tuning methods in plain English. Working with Frank not only makes your infrastructure better, it makes your people smarter. He was a great help setting up our infrastructure. Highly recommended.

Frank at RevSys provided us with excellent advice to help optimise our Django based app, which resulted in an impressive improvement in performance. Code-tuning recommendations came in an easy to digest format with ‘biggest bang for buck’ changes clearly marked. Recommend.

Working with both Frank and Jacob was pleasure. They were quick to respond to our needs, attentive to the details, and offered terrific support and knowledge sharing throughout the project. Knowing they are both leaders in their fields made collaborating with them to meet our requirements and trusting their ideas and creative solutions that much more easy. They are both really good guys to boot as well. I'd work with them again in a second.

RevSys and Frank Wiles have allowed The Wharton School at the University of Pennsylvania get off to an excellent start with our new language / framework of choice, Python / Django. He has trained us in best practices, went the extra mile with recommendations and even hopping into our code and configuration. We can’t recommend RevSys highly enough.

When we made the decision to standardize on Django and needed help jump starting a
team coming from diverse backgrounds, we looked for the best in the field; we
called RevSys. Jacob was a pleasure to work with both on the front end of
the engagement as we planned it all the way through the week of onsite training
and followup. I could not have been more impressed with his knowledge or his
ability to impart it to our team. He is a complete professional with an honest
direct approach. He puts a lot into his work and it shows. Years later, I am
proud to say we have one of the best Django teams in the U.S.A.
